Certified Ethical Hacker (CEH): Network Scanning

Network and information security professionals

Prerequisite
None

Expected Duration
90 minutes

Description
Network scanning refers to a set of intelligence gathering procedures hackers perform to identify hosts, ports, and other vulnerabilities in a network. By finding such vulnerabilities, a hacker can create an accurate profile of the target organization. An ethical hacker is a person who attacks an organizations security on behalf of its owners in order to discover vulnerabilities. Instead of taking advantage of these vulnerabilities, the ethical hacker reports them to the organization who can then put in place the appropriate countermeasures to protect themselves against malicious hackers. In this course, we look at network scanning, and the tools and techniques used. This course is the third in a series of courses which can used in preparation for the Certified Ethical Hacker 312-50 exam. The course has been developed in partnership with EC-Council and is based on their Ethical Hacking and Countermeasures course materials and labs.
